SHOULDER-BAG WATER-SPRAYING AIEPARATUSv Specification of Letters Patent. P te t d e t, 19, 1911,

Application filed December 17, 1910. Serial No. 597,801.

To all whom it may concern.

Be it known that I, DANIEL W. ADAMS,

.a citizen of the United States,residing at use in extinguishing forest fires which spread rapidly along the ground in the underbrush, dry leaves and grasses. Equipped with this outfit, the forest ranger may apply a, stream or spray of water directly to the ground or surface fire most effectively as he walks to the very edge of the burning e1n-- bers.

I am aware of the fact that other shoulder water-bags have been devised, but there has heel no provision by which they are enabled to expand during the operation of filling and permitting them'to be collapsed into a compact form when not in use, These and other objects are attained by means of apparatus hereinafter described and illustrated in the accompanying drawings, in which 7 Figure 1 is a side elevation of an apparatus embodying my invention; Fig. 2 is an end elevation, and Fig. 8 is .a top plan view of the same, showing the bag as it appears when expanded or filled; Fig. 4 is a top plan view, showing the bag collapsed; Fig. 5 is a side elevation, partly in section, showing the dcvelopable funnel and the funnel-support or mouth-piece; Fig. 6 is a plan view of the funnel when developed and flattened; and

. Fig. 7 is a longitudinal section of the spray nozzle.

The water-bag is preferably constructed of waterproof canvas having stifl front and back members or canvas plates 2, 2 which are sufliciently firm to maintain their proper shape. In order that the bag may expand as it is being filled with water and be collapsed into a small compass when it is empty, I connect the front and rear frame members by intermediate flexible canvas bellows folds 4, having each of the four sides formed into accordion plaiting. At

an intermediate point, and preferably midway between the side plates, I insert a funnel-support or mouth-piece 5, which may be secured by means of a tie-wire 7, binding the edges of the canvas surrounding the 'aperture into an annular groove. While I prefer to construct the mouth-piece of resinous wood, it may be made of other material. The I'lgld mouth-piece inserted in the flexible canvas bellows folds portion, insures a free open inlet at all times for the filling of the bag, and the entering water immediately expands the bag, whereas if the mouth-piece,

were flexible and could collapse, considerable difliculty would be experienced in the fillipg operation, causing considerable annoyance and serious delay.

In order that the apparatus may be exceedingly compact when not in use, I also provide a funnel 8 which may be developed and flattened when not in use into the. form shown in Fig. 6. vThe funnel is formed from an integral piece of leather, and the edges which are brought together when ready for use are provided with snap or glove fasteners 9. The apex of the funnel is placed over the mouth-piece and secured in position by meansof a raw-hide lacing or draw-string 1O.

The outlet connection is provided with a cut-off valve 12, and is connected to a hose 14 having aspray nozzle 15, which is preferably provided with a screw joint 16, to facilitate cleaning in case the nozzle becomes clogged.

In order that .the carrier may be'able to easily reach the cut-off valve and that the hose may be as short as possible, I slope the bottom of the bag toward one corner, to which the discharge outlet is connected. In the arrangement illustrated, the cut-off va'lve would be within easy reach of the right hand of the carrier and the hose would pass directly along his right side when the nozzle is held in the right hand. Supporting straps 18, secured to the front plate, pass around the shoulders held in position by th breast strap 20.

The operation of the apparatus will, be apparent from the foregoing description. When the apparatus is not in use, the front and rear members are pressed together, forcing the intermediate bellows fold portion into the folded position shown in Fig. 4, and the funnel may be flattened as in Fig. 6, so the entire apparatus may be formed f the carrier and are into a compact bundle and placed behind the saddle of a forest ranger.

. The many advantages to be derived from the use of my apparatus will be apparent to those who have had experience in fighting forest fires.

While I have described in detail the apparatus disclosed in the accompanying drawings for the purpose of disclosing one' embodiment of my invention, it will be evident that many changes may be made therein without departing from the spirit of my invention or from the scope of my claims, which are- 1. A shoulder-bag spraying apparatus, comprising a substantially rectangular water-proof bag having stifi' front and rear Walls and a collapsible intermediate portion closing all sides of the bag, a rigid funnel- ,support and a discharge connection secured respectively in the top and in the bottom of said intermediate portion, and a developable' funnel detachably mounted upon said funnel-support.

' 2. A shoulder-bag spraying apparatus, comprising a closed Water-proof bag having stiif front and rearwallsand a collapsible intermediate portion, the bottom of the bag sloping toward one side, and a rigid funnelsupport and a valved discharge connection secured respectively in the top and in the, bottom of said vintermediate portion, said discharge being located at the lower side thereof.

3. A shoulder-bag spraying apparatus, comprising a water-proof bag having stiff front and rear Walls and a' collapsible intermediate portion, the bottom of the bag slopmy hand in presence of two subscribing wit- .nesses.
